Application filed April 17, 1925. Serial No'. 25,279.

a Our invention relates .to ironing machines and an obgect of our improvements is to provlde an effectlve machme that is slmple 1n but little floor space; and one. that will move the material over a heated iron shoe at the same time keeping the material in contact witlnthe shoe, that will permit closing and opening the shoe independently of the rota- 10 tion of the feed roll, thus allowing the material to be pressed between the feed roll and the shoe without being mechanically moved across the surface of the shoe; and one that is adapted to iron or press tubular garments r or materials, in other words, a machine that has a full open end feed roll.

We secure these advantages and others in the apparatus shown in the accompanying drawings, in which longitudinal vertical section of an (apparatus embodying our invention. 1

detail sectional .view on the 3 -line 44; of Figure 1, looking in the direction of the arrows; the feed roll and the actuating sprocket wheel therefor being removed. Figure 5, is a detail sectional view showing the connection of the actuating rods to the shoe. i

Figure 6, is a detail elevation of the right hand end of the tube d, as shown in Figure 1.

Figure 7, is a detail vertical sectionof the feed roll and shoe at the left hand end thereof,

so as shown in Figure 1. i '1 a, a, are the end standards or uprights; these are formed of sheet metal pressed out so as to be hollow on their inner sides thus I This constitutes t e frame of the machine.

flanges (i (Fig. 6) construction, light in weight, that occupies Figure 1, is an elevation, mostly in detail able means, thussecuring the feed roll in extending from the wall of the casing k with- (Z, is a thin sheet metal tube, one end of which is out and turned outward to form This. tube extends through an aperture formed therefor in the right hand upright a toward the top thereof and the flanges d engage against an arm riveted or otherwise secured to the web of the said upright at the outer surface thereof, thus the tube is held rigidly in its horizontal position, as shown in Figure 1. p

f, is a shaft bearing in and extending be tween the foot pieces e, 6 Said shaft or rod connects foot pieces 6 and 6 together and serves to support the pedal which rocks about the same.

It, is a thin cylinder constituting the active portion of the feed roll. The cylinder h is provided with pressed out end pieces 71?, k which fit over collars h, which collars are adapted tofit and slide axially upon the supporting cylinder d. The left hand end of the supporting cylinder d is closed by a disk d fixed in the-end of said cylinder.

3', is a sprocket wheel bearing and adapted to turn upon the cylinder d-at its right hand end adjacent to the ,web of the upright a. j '2, are pins extending axially inward from the surface of the sprocket wheel near the periphery thereof and engaging in apertures k in the right hand end piece h of the cylinder h. 72. is a thin metal disk.

The sprocketwheel j is first slid into position along the surface of the supporting cylinder all, then the feed roll it is placed in position, as shown in Figure 1 so that the pins 3' engage through the apertures h The disk it is then placed in position and secured therein by a thumb screw d engaging through said disk and into the closure 03 or by other suitengagle position so that it may be easily detac ed.- Y

is, is a casingof box-like form-having its open'end engaging against the inner surface of the upright a at the right of the apparatus, 0- as shown'in Figure 1, The web of said upright servesto close the open end'of said casing. k is-a cylindrical spindle or arbor in said'casing.

m, is a sleeve engaging the spindle k and adapted to rotate thereon. m indicates sprocket wheel teeth upon the sleeve m. m, is

a worm wheel upon the sleeve m. n, is a worm engaging the teeth of the wheel m 110 p, is a pulley on the outer end of the worm n. 0, is an electric motor [secured to the inner surface of the. upright abelow the casing 70. 720 is a belt passing around a pulleyon the shaft of the motor oand around the pulley on the worm n.

' m y' is a sprocket chain engaging the teeth of the sprocket wheel m and ofthe sprocket wheel 7'. The feed roll it may be driven by the motor 0 through the gearing just described.

g, is the ironing shoe, this has an arcuate form in cross section at its upper surface to correspond to the form of the feed roll it.

The shoe 9 is preferably of cast metal and is provided with a central longitudinal conduit or passage g from which extends laterally in both directions small apertures 9 The gas is supplied through the pipe 7 (Fig. 1) to the passage 9 and passes outthrough the apertures g in both directions its lower end open. I A circular aperture is formed through the horizontal flange of a cross piece 0 axially in line and below each of the sockets g. In each of said apertures is placed a cup if having its lower-"end closed and its upper end turned over in a flange engaging upon'the ulpper surface of the cross piece 0. Each of the tubes t extends at its lower end .into the cup t and is adapted to slide axially therein. There is a spring at resting at its lower end within and upon the lower end of each of the cups t and engaging at its upper endagainst the upper end of a tube F. The springs to act to force the shoe 9 yieldingly toward the feedroll h.

'v, is a table extending between' the uprights J a in position to receive the articles to be ironed or pressedw before they pass under the feed roll. to, is a. sheet metal guide extending back of the machine in position to receive the articles as they pass out from beneath the feed roll and this is extended below the shoe .9 and under the same to a delivery point to underthe table '0 at the front of the machine Where the operator may receive the articles that have been through the machine. a

r, isa lever pivoted to the foot pie'ce f and adapted to oscillate in a horizontal plane.

This is turned upwardat its end inside of the foot piece g so that it'may be easily'a'ctw ated by the foot of the operator. 8, is a bolt that may normally be pulled forward by the spring s 'and' when in this position engage means of the connecting rod rs to disengage it from the ledge 6 g, are four rods connected at their lower ends to the oscillating pedal construction g, g and at their upper ends engaging the shoe g)at its four corners, as shown at 9, (Fig. 5.

.By pressing down upon the foot piece g, the shoe g is drawn downward away from the feed roll it and may be secured inthis position by the bolt 5. WVhen the bolt 8 is use, but may be enlarged for other. uses.

In the size for this purpose, the whole apparatus will weigh in the neighborhood of 100 pounds and the-entire length is only about two inches more than the length of the ironing shoe. The material to be acted upon is usually fed in the usual way between the rotatin cylinder k and the shoe 9, but articles of tubular form may be placed over the roll it by sliding them axially over said roll from the left hand side, as shown in Figures 1 and 7 Articles may be pressed by depressing the "shoe, placing the article upon the up er surface of the shoe and then allowing t e shoe to rise, then moving the shoe down again and-moving the article along and repeating the operation.

It will be observed that the shoe 9 has a resilient floating support so that it may adjust itself to unequal thicknesses of material above it or between it and the feed roll.

That the connection between the actuating 1 device and the shoe 9 is simple and direct so that the shoe may be pulled directly downward .and allowed to rise directly upward with a'eontrol motion.

What we claim is 1. In an apparatus of the kind described a frame, a feed roll in the upper part of said frame, a pedal apparatus at the'lower portion of said frame, a shoe in said frame extending beneath said feed roll, guides for said shoe,said shoe being adapted to move vertically, said pedal apparatus being connected immediately to said shoe 'to draw said shoe downward, and a spring restin upon said frame and acting to force said s we upward and supporting said shoe.
